A method where a first network node receives from a second network node a packet with a path identifier value in the header. A plurality of bearers associated with the path are determined based on the path identifier value and used to assign at least one resource to the packet before it is transmitted to a third network node based on the at least one resource.

The first grant and the second grant are overlapping. The method comprises determining a prioritized one of the first grant and the second grant and constructing a Medium Access Control (MAC) Protocol Description Unit (PDU) for the prioritized grant of the first grant and the second grant. According to certain embodiments, a method performed by a network node comprises transmitting a first grant and a second grant to a wireless device. The first grant and the second grant are overlapping. The method comprises receiving a transmission from the wireless device on a prioritized one of the first grant and the second grant.

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

Network architecture, methods, and devices for a wireless communications network

A method performed by a first node. The first node operates in a communications network. The first node determines, based on a header of a packet, a first number of hops. The first number of hops are the hops the packet has to traverse in the communications network to reach a second node in the communications network. The header of the packet indicates a second number of hops between the second node and a third node in the communications network in a first path. The first node obtains a wired backhaul connection to a core network of the communications network from the third node. The first node then initiates routing the packet towards the second node based on the determined first number of hops.

First node, second node, fourth node and methods performed thereby in a communications network

Methods, a transmitter device and a receiver device are provided for communication of media access control (MAC) protocol data unit (PDU). According to an embodiment, the transmitter device determines an MAC PDU including an MAC subheader and transmits the MAC PDU to a receiver device. The MAC subheader includes a second logical channel identity (LCID) field which is an extension of a first LCID field. A presence of the second LCID field is indicated by an indicator that is included in the MAC subheader.

Methods, transmitter device and receiver device for communication of MAC PDU

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

A method for transmission reliability comprises receiving, from a first network node at a second network node, a message indicating that a first connection between the first network node and a terminal device has failed. The message comprises an indication to initiate a second connection with the terminal device from the second network node. The method further comprises establishing, at the second network node, the second connection with the terminal device based on the message. The second network node comprises a third connection established before the first connection failed. The first connection carries data transmitted in the third connection before the first connection failed, and the second connection carries data transmitted in the third connection after the first connection failed. The method for interference coordination utilizes duplicated transmissions to secure data transmission and to prevent data loss in an unexpected system failure.

Method and apparatus used in transmission reliability

Embodiments herein relate to e.g. a method performed by a first communication device for controlling transmission of one or more data packets in a wireless communication network. The first communication device transmits an indication, to a second communication device, indicating one or more of the following: a maximum number of duplicates allowed to be transmitted for each data packet; type of duplication; a data radio bearer, DRB, for which duplication is configured; a radio link control, RLC, entity that is allowed to transmit a duplicate; an order of RLC entities in which the second communication device should transmit a first data packet and following duplicates; whether duplication is activated or deactivated for a DRB.

First communication device, second communication device and methods performed therein for controlling transmission

According to certain embodiments, a method in a wireless device () includes transmitting a protocol data unit (PDU) or segment of a PDU on a first link and transmitting the PDU or the segment of the PDU on a second link. One or more retransmissions of the PDU or the segment of the PDU are scheduled on the second link. A positive acknowledgment is received from a receiver. The positive acknowledgement indicates a successful receipt of the PDU or the segment of the PDU on the first link. In response to receiving the positive acknowledgement, the one or more retransmissions of the PDU or the segment of the PDU on the second link are cancelled.

Systems and methods for removal of duplicated packets for transmission

A method and a first network node of a wireless network, for handling paging of a wireless device. A Radio Access Network Area, RANA, which is supported by the first network node, is registered in a database by network nodes supporting the RANA, including the first network node. The network nodes that support the RANA are then identified in the database. When it is detected that a wireless device needs to be paged in the RANA, e.g. for receiving data, a paging message is distributed to the identified set of network nodes as an instruction to perform radio transmission of the paging message. Further, which is available to the network nodes throughout the wireless network. Thereby, any network node in the wireless network, such as the first network node, is able to perform distribution of a paging message to all network nodes that support a particular RANA, as registered in the database.

According to an aspect, a UE in an uplink split-bearer configuration is configured to transmit PDUs by a first RLC entity via a first uplink transmission path and/or by a second RLC entity via a second uplink transmission path. The UE determines a total amount of data volume from PDCP data volume and RLC data volume pending for initial transmission in the two RLC entities. The UE decides whether submission of PDCP data volume is allowed to either of the two RLC entities or to only the first RLC entity, based on whether the total amount of data volume meets or exceeds a first threshold. The UE also reports the PDCP data volume to both the first and second uplink transmission paths or only the first uplink transmission path, based on whether the total amount of data volume meets or exceeds a first threshold.
